Re: Comp Cam Spring Selection
Marcus & Lew, thanks for the info. Not sure where you looked up spring info but I spent some time on the Comps site and didn't see it. I like the idea of using the locator/cup to reduce spring size required. Now I can add new seals to the list. If it was as easy as replacing the springs I could do that without pulling the seal off the valve. I'll see what Comp comes back with but your numbers come in pretty darn close.
I've been working with Competition Products in Wisconsin, about 30 minutes drive for me. They said the best AFR can do is a special order 175# closed/450# open for hyd. rollers.
Thinking I might be on the edge of the roller tip limits, I will be putting a screen in the valley. I had already removed the casting flash in that area. I checked out the Crower Polylocks and they are short at .865" and just might work. Looked at ARP and they are 1.2" tall, not a chance. I have a set of stainless roller rockers and can do some fit-up before pulling that trigger.
I simply cant use a taller rocker cover. Distance between the cover and AC fan is just enough to sneak the heater hose through with a stock head. I even thought about dropping a spacer between the cover and head for assembly reasons. This just doubles my risk for leaks. I'm afraid the AFR might be taller in this area already. No room to drop the engine in the frame either. All this to use roller rockers...
Thanks guys for your input and experience. I've said it before, this site ROCKS!
